EDWARD HOLMES AND BRITAIN HOLMES, OF BUFFALO, NEW YORK.

MACHINE FOR MAKING VSTAVES.

SPECIFICATION forming part of Letters Patent No. 224,187, dated February 3, 1880.

l y Application filed April 24, 1879.

To all whom t may concern: Y

Be it known that We, EDWARD HoLMEs and iBErrAIN HOLMES, both of the city of Bualo,

in the county of Erie and State of New York, have jointly invented certain new anduseful Improvements in Machines for Making Staves, which improvements are fully set forth in the following specification and accompanying drawings, in which- ,Y

and 5 show the positions of a stave as one end.

reaches the inclined bed and the other end lleaves the horizontal bed.

The object of this invention is to provide the means for hollowing out the insides of staves so as to leave the ends the required thickness; and it consists of a suitable bed, cutting apparatus, and feeding device, in combination with an inclined bed for regulating the depth of the cut and its' distance from the ends of the sta-vc. y A

Our invention furtherconsists in `the process of hollowing out the inside of a stave by feeding it over a horizontal bed, under rotary cutters, and over an inclined bed, whereby the end of the sta-ve is `lifted atl the proper Vtime 'to reach the cutters at the required distance from the end, and continues so to rise until the necessary depth is reached, and is then carried forward in a straight line `under the cutters, having its support on the extreme ends ot' the beds until the opposite end reaches and passes along the horizonta-l bed, when it gradually recedes from the cutters, and then passes out of the machine, which causes that end of the stave to leave the cutters in a similar Way the first end approached them, so that both ends of the stave-may be cut alike, as will be more clearly hereinafter shown.

In the accompanying drawings, A represents theframe ofthe machine; B B', the

and both beds should be of the same length would be forced between it and the bed.

`means of the weights K K' L L', which are connected with said rollers, as shown. A smooth bar held down by weights or springs could be used as an equivalent, or a simple spring having its end pressing on the .inclined bed near its upper end, so that the stave In either case the pressure-rollers could be dispensed with and the same result Ohta-ined, and in some cases the weightof the stave alone would answer the purpose, the object being to hold the stave toward the beds and prevent it from beingV drawn too far into the cutters'.

M M' represent the cutter-heads and cutters. They are driven by a belt and pulley, N.

The upperfeeding-roller is held by the arms P P' and Weight R. Instead of the feedingrollers, a pushing device, a belt, or an endless chain may be used for the purpose, or the staves maybe pushed into and through the machine one after the other, so that'wheu a cheaper machine is required the feeding rollers may be dispensed with, andthe beds H H' may be made in one piece, if desired.

We claim as our invention- 1. In a machine for hollowing out the insides of staves, the combination, with a rotating cutter, of a horizontal bed, H, having an inclined part, H', for .raising the staves to the cutters, substantially in the manner and for the purposes specified.

2. The combination of a .rotating cutter, the

.horizontal bed H, and inclined bed H',`and ysuitable vdevices for feeding and preventing thestaves from being drawn into the cutters,

substantially as specified.
